Large prefabricated box girder top plate hoisting anti-cracking device and anti-cracking method thereof
According to the large prefabricated box girder hoisting anti-cracking device and the anti-cracking method thereof, hoisting holes are formed in the two sides of a prefabricated box girder and used for hoisting the prefabricated box girder, and in the hoisting process, horizontal fine cracks are likely to be generated at the joints of the top face and the bottom face of the box girder used for forming the hoisting holes, and the quality of the prefabricated box girder is affected. The hoisting anti-cracking device is detachably installed on the pure top plate side of the prefabricated box girder, through the arrangement of the hoisting anti-cracking device, the connecting strength of the connecting position of the top face of the box girder and the bottom face of the box girder is enhanced, the overall stress of the prefabricated box girder is more uniform, cracks are prevented from being generated on the prefabricated box girder in the hoisting process, and the quality of the prefabricated box girder is guaranteed.
大型预制箱梁吊装防裂装置及其防裂方法，预制箱梁的两侧形成吊装孔，用于对本预制箱梁进行吊装，在吊装过程中，用于形成吊装孔的箱梁顶面、箱梁底面连接处容易产生水平的细裂纹，影响预制箱梁的质量，本发明中，在预制箱梁的单纯顶板侧可拆式安装有吊装防裂装置，通过吊装防裂装置的设置，加强箱梁顶面、箱梁底面连接处的连接强度，使得预制箱梁的整体受力更为均匀，从而防止起吊过程中在预制箱梁上产生裂纹，保证预制箱梁的质量。
